ADJUSTABLE SHELF-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 754,817, dated March15, i904. Application filed April 30,1902. Serial No. 105.389. (n5model.)

To all whmn it may concern:

Be it known that I, EDWARD G. SCHRIEFER, a citizen of the United States,residing at Oincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in AdjustableShelf-Supports, of which the following is a specification.

It is the object of my invention to provide new and useful improvementsin adjustable shelf-supports; and my invention consists in the parts andin the construction and arrangement and combinations of partshereinafter more fully described and claimed.

The subject-matter claimed in the present application is also shown anddescribed in my applications, Serial Nos. 92,461, 92,462, and 92,463,filed February 3, 1902. I have also shown, described, and broadlyclaimed an adjustable shelf-support of the character of the deviceherein shown, described, and claimed in a separate-application of evendate herewith, being Serial No. 105,388, to all of which applicationsreference is respectfully made.

In the drawings, Figure '1 represents a perspective view of my improveddevice in connection with a case, having the top and bottom and frontedges of the case broken away. Fig. 2 is a verticalseotion taken throughthe sides of the case and shelf on a line corresponding to the line a; wof Fig. 4 with the shelf in raised position and showing the sides inspread relation. Fig. 3 is a similar view showing the shelf seated andthe sides in proper relative position. Fig. 4 is a plan View of myimproved device with the side shown in horizontal cross-section and theshelf omitted. Fig. 5 is a perspective viewof the con nected support.Fig. 6 is a bottom view of the shelf, showing the recesses and engagingmeans for the support. Fig. 7 is a perspective view of a single support.

1 represents the back of a case, and 2 the sides. 3 is a shelf.Shelf-strips 4 are secured to the sides, the strips having openings 5and may also have a groove 6, extending longitudinally of the strips andreceding outwardly from the inside of the case. In the depressed portionof each groove the openings 5 are located. The strips are suitablysecured to the case, and a clearance-groove 7 is located in rear of theopenings. The strips are preferably countersunk into the sides intogrooves 8. so as to leave the outer edgesof the strips flush with thesides. Supports 9 are adapted to support the shelf. The supportpreferably comprises an upper book 10 and a lower hook 11, adapted totake intotheopenings 5, lips 12 of the hooks taking against the rearface of the strips 4. A shank 13 of the support is received by thegroove 6. The seats of the hooks preferably rest-upon the lower edges ofthe openings 5, with the inner sides of the hooks taking against theouter sides of the shelf-strips. preferably the longer, so thatthesupport may be held cantingly for readily finding and inserting thesame into the lower opening, as shown in dotted lines in Fig. 2, whenthe upper hook may be readily inserted into the upper opening. The hooksprovided at the upper and lower part of the support distribute thepulling strain of the shelf on the side when seating the shelf, ashereinafter stated. The supports are provided with recesses 14 forreceiving projections 15 on the shelf, the recess preferably being ahole punched into the support and the projection a screw or nail driveninto thebottom of the shelf and preferably provided with an inclinedface 16,.extending outwardly toward the sides, so that the projectionmay readily find its opening or aperture and while the shelf is beingseated, as by pressure upon the top of the shelf, mayact for drawingtogether the side and shelf, the. hooks acting to draw the side intoposition with the support. In the form shown the lower hooks 11 areformed of the metal removed for forming the holes The lower hook is i14, the whole of the support being formed of and projections between thesupports and shelf prevent relative outward movement of the sides, andthe inclined face on the projection draws the sides toward the shelfwhile seating the shelf, thereby securing the whole firmly together andholding or limiting the sides of the case against sidewise displacementand bulging.

I have shown each side provided with a plurality of shelf-strips andhaving a plurality of shelf-supports, the latter connected by a web 17It is obvious, however, that this web may be omitted and a separateshelf-support be provided for each corner of the shelf, theshelf-support then taking the form shown in Fig. 7 The bottoms of theshelves may also be provided with rabbets 18 for accommodating theshelf-supports.

I claim 1. In an adjustable shelf-support, the combination of a support,means for adjustably connecting said support to a'side, said supporthaving an opening, the sides, and a shelf adjustable up and down betweenthe same, said shelf having a projection projecting downwardly from theunder side of the shelf between the ends of the shelf and having aninclined face extending transversely to the side taking into the openingand relatively drawing the side and shelf toward each other whileseating the shelf on said support.

2. In an adjustable shelf-support, the combination with the sides and ashelf, of a support for each end of the shelf, means for adjusting thesupports and shelf up and down between the sides and connecting saidsupports to said sides, each of said supports having a recess takingunder the shelf, said shelf at each end having a projection projectingdownwardly from its under side between the ends of the shelf, and saidprojections each having an inclined face and taking into the respectiverecesses, and thereby relatively drawing the side and shelf toward eachother by pressure applied on the shelf.

3. The combination of a pair of sides each having a pair of grooves inits inner face, four shelf strips, one in each of said grooves andextending up and down on the side, each of said shelf-strips having agroove receding outwardly and a flange at each side of said grooveprojecting sidewardly from said groove in substantially the plane of theinside face of said side, a pair of shelf-supports releasable from saidshelf and sides, one at each end of the shelf extending beyond said endfrom said shelf-strips, said shelf-strips having openings for receivingsaid supports, said shelfsupports each having a recess under the shelfand said shelf at each end havinga projection extending downwardly fromthe under side of said shelf and between the ends of said shelf intosaid recess, each of said projections having an inner inclined facetaking against the inner wall of said recess.

4:. The combination with a pair of sides and a shelf, of shelf-stripssecured to and extending up and down on each side at the inner facethereof and shelf-supports, with meansthereon engaging said shelf-stripsfor adjustably positioning said supports at various elevations on saidshelf-strips, said shelf-supports extending from said sides under theends of the shelf, each shelf-supporthaving a recess under the shelf,said shelf having a projection at each end between its ends extendingdownwardly from the bottom of said shelf and releasably engaging ashelf-support at each end of the shelf, said projections having innerinclined faces engaging the inner walls of said respective recesses.

5. In combination with a pair of sides and a shelf, a sheet-metalshelf-support having a hook struck from its body and thereby forming anopening,and a peg on the bottom of the shelf taking into said opening,said peg having an inner inclined face engaging the inner wall of saidopening.
